Corrective Action
On October 29, 2010 at 14:00 when the seal cooler vent valves were discovered to be open, Core Alterations were already temporarily suspended for an unrelated problem with the Spent Fuel Pool bridge crane.
On October 29, 2010 at 15:20, containment integrity was moved back to inside containment when the relief valve was verified installed and intact per the site refueling integrity procedure. Core Alterations were recommenced on October 29, 2010 at 23:44.
The Unit 1 site procedure governing refueling integrity was corrected for both trains of RHR. The corresponding procedure on Unit 2 was also revised.
